SPMT090304 T5115 Turning Insert (ISO 090304) – Square 09, 0.4 mm Corner Radius (Tungaloy)

The SPMT090304 T5115 is an ISO‑normed square turning insert intended for external and internal turning, engineered as a universal grade for cast iron with a one‑sided chipbreaker and a cylindrical locating hole with a single‑side countersink.

• ISO square insert SPMT090304, 0.4 radius
• CVD-coated carbide grade T5115 for cast iron
• One-sided chipbreaker with 11° relief angle

Consistent cutting performance for cast-iron turning

The indexable plate delivers reliable cutting behaviour thanks to the CVD-coated carbide composition of grade T5115, which balances wear resistance and edge stability for cast-iron machining. The engineered coating improves flank wear resistance and reduces built-up edge formation, so the tool life is extended under typical turning loads. For production environments, the result is fewer insert changes and more predictable batch yields, which supports efficient planning and lower machining costs.

System compatibility and secure clamping for reproducible results

Designed as part of the ISO turning insert system, the square 09 format and the cylindrical hole with a one-sided countersink (40°–60°) ensure secure location in compatible holders. The insert’s geometry—including the 11° relief angle and 3.18 mm thickness—matches standard ISO interfaces, enabling straightforward integration into existing toolholders and tool posts. This compatibility reduces setup time and simplifies inventory management for workshops and production lines.

Productivity and economical operation through optimised chip control

The insert’s one‑sided chipbreaker is tuned for chip control in cast iron, producing short, consistent chips that evacuate reliably even in interrupted cuts. Combined with the modest 0.4 mm corner radius, the geometry supports stable cutting with reduced vibration and better surface integrity. The net effect is higher productivity: stable edge life plus improved chip flow reduces downtime for clearing and tool changes, delivering measurable process gains across repeating operations.

Practical handling and application guidance

The square form factor allows multiple indexings per insert, improving utilisation and cost efficiency in serial turning. The ISO designation and detailed dimensions mean selection of an appropriate holder should consider form, clearance angle, tolerance class and fastening method to guarantee correct seat and clamping. For finishing or semi‑roughing passes on cast iron, the grade's balanced properties permit flexible feed and depth settings while preserving edge condition; for unfamiliar applications, a brief trial cut is recommended to confirm ideal parameters.

FAQ

Which materials is this insert designed for?
The SPMT090304 T5115 insert is formulated as a universal grade for cast iron, offering a balance of wear resistance and edge stability for external and internal turning of grey and nodular cast irons.

How is the insert secured in the toolholder?
The insert locates via a cylindrical hole with a single‑side countersink and is clamped in ISO‑compatible holders; correct holder form, clearance angle and fastening ensure reproducible seating for the SPMT090304.

What advantages does the T5115 coating provide?
The CVD coating on the T5115 grade increases flank wear resistance and helps prevent built‑up edge on cast iron, improving insert life and part quality under typical turning conditions.

Can the square insert be indexed multiple times?
Yes, the square geometry permits several indexings per insert, which increases utilisation and reduces tooling costs when machining repetitive features.

Is the insert suitable for finishing passes?
The modest 0.4 mm corner radius and balanced grade make the insert suitable for both finishing and light to moderate roughing on cast iron, depending on cutting parameters and machine stability.
